Reelbox eHD DA is poor, so there is no any reason to use analog output. HDMI output is ok, but there is couple items to remember: chipset have only one scaler/video processor. So if analog output is active, video is for it. HDMI gets same -> video is not pixel to pixel, it is always scaled! To get right quality out of HDMI, turn off analog output completely.
Second issue is caused by HDMI itself, there is very few displays with 576i/480i support. With HDMI eHD reads display capabilities and end result is most of cases 576P/480P even that ui tels 576i/480i. eHD internal processing for i->P is poor, so SD looks quit bad.
When you get combination where eHD outputs pixel to pixel 576i (or what native resolution of video is) signal over HDMI/DVI and TV scales it properly, quality is perfect. Much beter than FF card with RGB, it is clear with comparison how DA-AD process lost one bit of every color channels.
If reelbox-3 plugins would work better (working FF/FR, no delays on replay commands) it is the best video output currently. It outputs original video/audio as it is with out micro stuttering.
Here is proper settings for eHD, when you have HDMI/DVI display and it support all resolutions (576i, 720p and 1080i in Europe)
Output: HDMI
Analog Output: off
Display Type: 16:9
Aspect Rations: Fill to Aspect
Resolution: 1080
Refresh Rate: 50Hz
Deinsterlacer for SDTV: Off
Resolution change: Media resolution
OSD scaling: Fill to screen
With proper display, digital video is now 1:1 on pixel/frame level.
